Barney Frank, the retired Democratic Rep. from Massachusetts, spoke with Isaac Chotiner of Slate in an interview published on Wednesday. Frank, who served in the House from 1981 to 2013 and was chairman of the House Financial Services Committee from 2007 to 2011, said “Bernie Sanders has been in Congress for 25 years with little to show for it in terms of his accomplishments”.

Frank also commented on his frustration with Democrats who are outspoken about their political frustrations but don’t show up to vote. “I’m particularly unimpressed with people who sat out the Congressional elections of 2010 and 2014,” he said, “and then are angry at Democrats because we haven’t been able to produce public policies they like.” Frank explained that their failure to vote contributes to the public policy problems, so they in turn blaming other people for their own failure to vote. “And then it’s like, “Oh look at this terrible system,” but it was their voting behavior that brought it about,” Frank said.

Not only is Barney Frank frustrated with the voters, he also has frustration with the voting system. The caucuses, Franks says, are the least democratic political operation in America. “They cater to the people who have a lot of time on their hands, and what’s interesting is Sanders is the nominee of the caucuses and Hillary is the nominee of the primaries,” he explained.

Barney Frank, who was one of the main architects of the Dodd-Frank act, which regulates Wall Street, thinks Sanders is too harsh on the financial system. “I do think that he overstates it when he says, “they’re all corrupt.” It’s simply not true,” he said. Frank believes that Sanders gets a pass from the media in terms of his record in the senate. “Other than Glass-Steagall, what did he propose in 2009 and 2010 when he was a senator when we were dealing with this? The answer is nothing.”
